ATTACHMENT FOR MOWIN'G-MACHINES.

Specification of Letters Patent. Pattenfjfid Sept. 28, 1%15.

Application filed September 14, 1914. Serial No. 861,731.

To all whom it may concern Be it known that I, VVILLIAM ELERY, a citizenof the United States, residing at Menlo, in the county of Guthrie andState of Iowa, have invented a new and useful Attachment forMowing-Machines, of which the following is a specification.

The object of my invention is to provide an attachment for'mowingmachines whereby thepitman for imparting the motion to the sickle may bequickly, easily and securely fastened to the cross-head of the sickleand the wrist-pin of the crank wheel, without the use of tools, bolts orthe like.

Still a further object is to provide such an attachment for securing thesaid pitman as above set forth, in such a manner as to take up all playbetween the parts at the cross-head and also at the'wrist-pin.

Still a further object is to provide such a device that can be moved.

My invention consists in certain details, in the construction,combination and arrangement of the various parts of the device, wherebythe objects contemplated are attained, as hereinafter more fully setforth, pointed. out in my claims and illustrated in the accompanyingdrawings, in which Figure 1 shows a front elevation of the mowingmachine equipped with an attachment embodying my invention. Fig. 2 showsa top or plan view of my improved attachment installed in position. Fig.3 shows a detail sectional view taken on the line 3-3 of Fig. 2. Fig. 4shows a detail view of the upper end of the pitman and the device forfastening the same in position. Fig. 5 shows a detail view of the hookand handle for securing the parts together.

in the accompanying drawings 1 have used the reference numeral toindicate the axle of a mowing machine, on which are the wheels 11.

Suitably mounted is the shaft 12 operated from the wheels 11, carryingthe crankwheel 13 on which is a wrist-p n 14.

Suitably mounted is the sickle bar 15, slidably mounted on which is thesickle 16, having a cross-head 17' on which is the lug 18.

Mounted on the lug 18 is a short shaft 19, which extends beyond said lug18 in opposite directions.

The pitman 20 is placed between the wrist-pin 14 and the shaft 19. One.end of the pitman is bifurcated at 21 to receive the quickly and easilyrein Fig. 1.

two ends of the shaft, and is suitably formed to receive and bearagainst the shaft 19. The other end of the pitman at 22 is concave tofit against the wrist-pin 14.

For locking the pitman 19 in its position ust described as shown in Fig.1, I have provided the following means: A rod 23 provided with abifurcated claw or end 24, the members of the bifurcated end 24 beingbent around to form hook devices, as shown by the dotted lines in Fig.3, which devices receive the. shaft 19. The rod 23 extends upwardlytoward the wrist-pin 14 adjacent to the pitman 20. Secured to the upperend of the rod 23 is a powerful coil spring 25., Secured to the coilspring 25 is a short rod 26, secured to the upper end of which areparallel spaced bars 27 which are pivoted to the rod 26-by means of thepin 28. The upper ends of the plates 27 are pivoted together in theirspaced position by means of the pin 29. Pivotally mounted on the pin 29;between the plates 27 is a hook 30 having a handle 31. A rod 32 isprovided with a suitablehook member 33 at its end, adapted to receivethe wrist-pin 14, and extends downwardly adjacent to the pitman 20. Thelower end of the rod 32 is provided with screw threads. Adjacent to'theend of the rod 32 is a rod 34, the upper end of which is screw threaded.The screw threads on the rods 32 and 34 are made in opposite directionsto receive a turn-buckle nut 35, the opposite ends of which are providedwith right and left hand screwthreads. The free end -of the rod 34 formsa hook 36. The rod 34 is "provided with a guiding device 37 to receivethe-handle 31 in one position of its movement.

in the practical use of my improved attachment the pitman 20 is placedin position with its ends against the pin 19 and the pin 14. ll he rods23 and 32 are placed in position receiving the pins 14 and 19, thespring 25 is secured to'the rod 23and the rod. 26,

the rod '34 is installed in position, the handle '31 is then turned overto position adjacent to the rod 26 until its hook or portion 30 engagesthe hook portion 36,- when the handle 31 .is used as a lever to stretchthe spring 25 andis turned over until the hook 30 and handle 31 rest inthe osition shown The parts will t on be held in this position duringthe operation of. the ma chine.

It will be understood that the parts 23,

25, 26, 27 and 30 are secured together, and the parts 34, 35, and 32 aresecured together so that the device when in actual use is composed oftwo parts. The attachment may be quickly and easily installed inposition or removed therefrom so that it is a simple matter to connector disconnect the sickle with or from the wheel 13. On account of thefact that the attachment is held in position by the resiliency of thespring 25 the pitman 20 is always held firmly against the pins 14 and'19 and the hook members 33 and 24 are also held firmly in engagementwith said pins, I

In practically all of the mowers now in use, one objection to the,construction employed lies in the Iactvthat the bearings where thesicklecross-head connects with the pitman, and where the said pitman connectswiththe gearing device such as the wheel 13, allow some play of theparts which on account 'of the very rapid motion which must be :impartedto the sickle, become heated. This difiiculty is -very largely avoidedby my construction hereinbefore set forth, whereby the play between. theparts is prevented.

I appreclate the fact that some: changes may be made in the details ofthe construction of my attachment, and it ismy intention to cover bythis application 'any such changes in construction which maybe includedwithin the scope of my claims.

I claim as my invention: 7

- 1. In a device of the class described, two movable members spacedfromeach other, a pitman received between parts of the re- 'spective movablemembers and bearing against said parts, hook members engaging saidparts, and yielding means for connecting said hook members and drawingthem together for holding said pitman in its inciprocating member andbearing against said parts, hook members receiving said pin and aportion of said reciprocating member re-,

spectively, and means for connecting said hook members and yieldinglydrawing them toward each other, "said means including a resilient deviceand means for stretching said resilient device and locking said hookmembers together.

3. In a device ofthe class described, two movable members spaced fromeach other, a pitman received between parts of the respective movablemembers and bearing against said parts, hook members engaging saidparts, and yielding means for connecting said hook members and drawingthem together for holding said pitman in its installed position, saidmeans including coacting engaging devices capable in one position ofengaging each other and'adapted to be moved into position for stretchingsaid yielding means and to be locked in said position.
